Allen-Bradley 2711-B5A16 PanelView 550 HMI Display

Allen-Bradley 2711-B5A16 PanelView 550 standard operator terminal provides a compact 5.5-inch monochrome HMI display with both keypad and touch input, designed for local operator interaction on legacy AB PLC systems. The unit communicates over RS-232 (DF1) to compatible controllers and includes a dedicated RS-232 printer port for printouts, all housed in the PanelView 550 enclosure and powered from AC mains. The display resolves 256 by 128 pixels, delivering simple graphics and text screens suitable for basic alarm banners, setpoints, and run-time messages. This particular 2711-B5A16 is a refurbished unit with FRN 4.46, intended as a drop-in replacement for existing PV550 installations and compatible with SLC 500/PLC-5 family systems that use DF1 communication.
